To detail-route a placed DEF, provide the placed DEF, tech LEF, and cell LEF paths to generate a routed DEF. This process applies QRouter to complete the detailed routing needed before DRC and signoff.
Detail routing requires a placed DEF, tech LEF, and cell LEF as inputs, along with the design_name. The workflow outputs a routed DEF, configuration file, log file, and a list of failed nets.
Detail routing is needed after floorplanning and placement are complete. It produces the routed DEF required to proceed with downstream DRC checks and timing signoff verification.
You can verify detail routing completion by checking the valid flag and error output. Additionally, the tool generates a failed_nets list to identify any specific nets that did not route correctly.
No, QRouter requires both a tech LEF and a cell LEF to perform detail routing. Both LEF files must be provided alongside the placed DEF to successfully generate the routed DEF output.
If detail routing fails, check the failed_nets output list to identify the problematic nets. The generated log_path provides detailed routing logs to help diagnose the specific causes of the routing failures.
